What is the typical slice thickness for a CT scan of the body?

The typical slice thickness for a CT scan of the body is primarily influenced by the need for a balance between image quality and the amount of radiation exposure. A thickness of 5 mm is commonly used for various types of body scans, providing a good compromise that allows for detailed visualization of anatomy while maintaining an efficient scan time and minimizing patient dose.

Thinner slices, such as 1 mm and sometimes even 3 mm, are often used in specific situations where more detail is needed, such as in imaging small structures or for certain diagnostic protocols. However, for routine body scans, a slice thickness of 5 mm is generally regarded as sufficient to capture adequate anatomical detail without unnecessary complexity or increased radiation exposure. The 10 mm thickness, while it may be utilized in certain cases, is less common for routine examinations as it may compromise the resolution of finer anatomical details.
